This is the Dakine Heli Pack which is a bit smaller than the Heli Pro (about 660 cu. inches). Perfect size for holding your lunch, an extra layer/gloves, shovel, etc. Has a sleeve for a water bladder with a port in the shoulder strap for easy access. Gear loops on the front. Hip and chest straps. Capable of carrying a pair of skis but not the best. Extremely durable backpack. This one is from 2008 or so, but it's in perfect functional condition. No rips, frays, or missing parts. The interior of the small top pocket has some ink stains from a pen that leaked, and there is normal cosmetic wear on the outside but that's it. $55 shipped to you.
